Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of scrap steel shavings processing technology, and more specifically, to a scrap steel shavings pressing device for steelmaking. Background Technology

[0002] Metal shavings are inevitably generated during metal processing. These shavings are in a loose state and take up storage space. In steelmaking, the proper addition of scrap steel can not only effectively reduce production costs but also reduce dependence on ore resources to some extent, aligning with the concept of sustainable development. Metal shavings can be added as scrap steel in converter steelmaking to lower the temperature of molten iron. However, in practice, the space in the scrap steel hopper is limited, and the metal shavings are in a loose state. Adding them directly to the converter as scrap steel can have several adverse effects. Firstly, it will affect the amount of scrap steel added; secondly, it may cause steel jamming accidents during converter smelting.

[0003] Current technology has significant drawbacks: directly adding loose metal shavings as scrap material to the converter for smelting occupies a large amount of space in the scrap hopper. This not only limits the amount of scrap added but also increases the difficulty for operators when adding scrap. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a steelmaking shavings scrap briquetting device, which solves the technical problem in the prior art that directly adding fluffy metal shavings as scrap material to the converter for smelting would occupy a large amount of scrap hopper space.

[0005] According to one aspect, at least one embodiment of this disclosure provides a steelmaking scrap shredder pressing device, comprising:

[0006] The frame has a vertically arranged first pressing chamber;

[0007] A feeding cylinder is mounted on the frame and has a feeding channel leading to the first pressing chamber. The feeding channel is used to feed the shredded material into the first pressing chamber.

[0008] A rotating plate is rotatably mounted on the frame. After the rotating plate rotates, it connects or disconnects the first pressing chamber from the feeding channel.

[0009] The pressure plate is raised and lowered on the frame. After being raised and lowered, the pressure plate extends into or is not extended into the first pressing chamber. After extending into the first pressing chamber, the pressure plate is used to shred the dough.

[0010] For example, in a steelmaking scrap shredder pressing device provided in at least one embodiment of this disclosure, there are two rotating plates, each with a clearance groove. After the two rotating plates are rotated to a horizontal state, the connection between the first pressing chamber and the feeding channel is canceled, and the two clearance grooves form a clearance hole, through which the pressing plate passes.

[0011] For example, in a steelmaking scrap shredder pressing device provided in at least one embodiment of this disclosure, the first pressing chamber has a first opening and further includes:

[0012] A base, on which the frame is mounted;

[0013] The first semi-circular arc plate is slidably mounted on the base;

[0014] The second semi-circular arc plate is slidably disposed on the base. After the first semi-circular arc plate and the second semi-circular arc plate approach each other, they form a second pressing cavity. One end of the second pressing cavity is connected to the first pressing cavity through the first opening.

[0015] For example, in a steelmaking shredded scrap steel pressing device provided in at least one embodiment of this disclosure, the base has a transverse channel, the second pressing chamber has a second opening, and the other end of the second pressing chamber communicates with the transverse channel through the second opening. The steelmaking shredded scrap steel pressing device further includes:

[0016] A pressure plate is disposed within the transverse channel, and the pressure plate is located below the second pressing chamber. The pressure plate and the pressure plate are used to press the shredded material.

[0017] For example, in a steelmaking shavings scrap pressing device provided in at least one embodiment of this disclosure, the pressure plate is slidably disposed in the transverse channel, and the second opening is opened or closed after the pressure plate slides. The steelmaking shavings scrap pressing device further includes:

[0018] The first telescopic member is disposed on the base and located on one side of the transverse channel. The first telescopic member is used to drive the pressure plate to slide.

[0019] For example, in a steelmaking scrap shredding and pressing device provided in at least one embodiment of this disclosure, the first semi-circular plate and the second semi-circular plate are slidably and vertically arranged on the base, the transverse channel has a pressing channel and a discharge channel arranged in sequence, the pressing channel is located below the second pressing chamber, and the pressure plate slides into the pressing channel to press the shredded scrap with the pressure plate.

[0020] For example, in a steelmaking scrap shredder pressing device provided in at least one embodiment of this disclosure, the cross-sectional area of ​​the discharge channel is larger than the cross-sectional area of ​​the extrusion channel, and the first telescopic member is located on the side of the extrusion channel away from the discharge channel.

[0021] For example, in a steelmaking scrap shredding and pressing device provided in at least one embodiment of this disclosure, the frame further has a receiving cavity and a guiding cavity, the receiving cavity, the guiding cavity and the first pressing cavity are connected sequentially from top to bottom, the feeding channel has a feeding port, and the feeding port and the rotating plate are located in the receiving cavity.

[0022] For example, in a steelmaking scrap shredder pressing device provided in at least one embodiment of this disclosure, the cross-sectional area of ​​the guide cavity decreases sequentially from top to bottom.

[0023] For example, in a steelmaking scrap shredder pressing device provided in at least one embodiment of this disclosure, the base has an installation groove, and the first semi-circular arc plate and the second semi-circular arc plate are lifted and slidably disposed in the installation groove.

[0024] The beneficial effects of the embodiments disclosed herein are as follows:

[0025] In this disclosure, when it is necessary to feed shredded material into the first pressing chamber, the rotating plate is rotated, connecting the first pressing chamber with the feeding channel, and the shredded material enters the first pressing chamber through the feeding channel. When a certain amount of shredded material is fed, the rotating plate is rotated to disconnect the connection, and then the pressure plate is driven to descend, so that it extends into the first pressing chamber to squeeze the shredded material and press it into a cake shape.

[0026] This invention features a simple structure, with the overall device consisting of basic components such as a frame, feed cylinder, rotating plate, and pressure plate, making it easy to manufacture and install. The switching between feeding and extrusion processes is controlled by rotating the rotating plate, while the lifting and lowering of the pressure plate achieves the extrusion of shavings. Operation is simple and easy to understand. The design of the feed cylinder and feed channel enables rapid and stable delivery of shavings to the first pressing chamber, improving work efficiency.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0036] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] like Figures 1-2 The diagram illustrates a steelmaking scrap shredding and pressing device according to an embodiment of this disclosure. The device includes a frame 1 with a vertically arranged first pressing chamber 11; a feed cylinder 2 mounted on the frame 1, having a feed channel 21 leading to the first pressing chamber 11, which is used to feed shredded scrap into the chamber; a rotating plate 3 rotatably mounted on the frame 1, which, after rotation, connects or disconnects the first pressing chamber 11 from the feed channel 21; and a pressing plate 4 is vertically mounted on the frame 1, extending into the first pressing chamber 11 to compress the shredded scrap.

[0038] For example, such as Figure 1 As shown, when it is necessary to feed shredded shavings into the first pressing chamber 11, the rotating plate 3 is rotated, connecting the first pressing chamber 11 with the feeding channel 21. The shredded shavings enter the first pressing chamber 11 through the feeding channel 21. When a certain amount of shredded shavings has been fed, the rotating plate 3 is rotated to disconnect the connection, and then the pressing plate 4 is driven to descend, so that it extends into the first pressing chamber 11 to squeeze the shredded shavings and press them into a cake shape.

[0039] This invention features a simple structure, with the overall device consisting of basic components such as a frame 1, a feed cylinder 2, a rotating plate 3, and a pressure plate 4, making it easy to manufacture and install. The switching between feeding and extrusion processes is controlled by rotating the rotating plate 3, and the extrusion of the shavings is achieved by raising and lowering the pressure plate 4. The operation is simple and easy to understand. The feed cylinder 2 and the feed channel 21 enable rapid and stable delivery of shavings to the first pressing chamber 11, improving work efficiency.

[0040] In some examples, there are two rotating plates 3, each with a clearance groove 31. After the two rotating plates 3 are rotated to a horizontal state, the connection between the first pressing chamber 11 and the feeding channel 21 is canceled, and the two clearance grooves 31 form clearance holes 32, through which the pressing plate 4 passes.

[0041] For example, such as Figure 1As shown, when feeding is required, the two rotating plates 3 are rotated to connect the first pressing chamber 11 with the feeding channel 21, allowing the shavings to enter the first pressing chamber 11. After feeding is complete, the two rotating plates 3 are rotated to a horizontal position, disconnecting the connection between the first pressing chamber 11 and the feeding channel 21. Simultaneously, the two clearance grooves 31 form clearance holes 32. Then, the pressure plate 4 is driven to descend, passing through the clearance holes 32 and entering the first pressing chamber 11 to compress the shavings. Subsequently, the feeding cylinder 2 continues to deliver shavings, which are temporarily stored above the rotating plates 3. After the shavings are compressed into a cake by the pressure plate 4, the rotating plates 3 rotate, connecting the feeding channel 21 with the first pressing chamber 11, and the shavings temporarily stored above the rotating plates 3 fall into the first pressing chamber 11.

[0042] The two rotating plates 3 can control the connection and disconnection between the first pressing chamber 11 and the feeding channel 21, preventing leakage of shredded material. The clearance hole 32 allows the pressure plate 4 to pass through the rotating plates 3 and enter the first pressing chamber 11 for pressing. This achieves continuous shredded material feeding without affecting the pressing process.

[0043] In some examples, the first pressing chamber 11 has a first opening 111, and the frame 1 is mounted on the base 5; the first semi-circular plate 6 is slidably mounted on the base 5; the second semi-circular plate 7 is slidably mounted on the base 5, and the first semi-circular plate 6 and the second semi-circular plate 7 are brought close to each other to form the second pressing chamber 71, and one end of the second pressing chamber 71 is connected to the first pressing chamber 11 through the first opening 111.

[0044] For example, such as Figure 2 As shown, after the shredded material is squeezed by the pressure plate 4, the resulting cake presses against the side walls of the first pressing chamber 11 and the second pressing chamber 71. After the shredded material in the first pressing chamber 11 and the second pressing chamber 71 is initially squeezed, the cake remains in the second pressing chamber 71. In order to facilitate material discharge, the first semi-circular plate 6 and the second semi-circular plate 7 are moved away from each other to reduce the friction between the first pressing chamber 11 and the cake, thus facilitating material discharge.

[0045] In some examples, the base 5 has a transverse channel 51, the second pressing chamber 71 has a second opening 711, the other end of the second pressing chamber 71 is connected to the transverse channel 51 through the second opening 711, the pressure plate 8 is disposed in the transverse channel 51, the pressure plate 8 is located below the second pressing chamber 71, and the pressure plate 8 and the pressure plate 4 are used to extrude shredded material.

[0046] For example, such as Figure 1As shown, before the shredded material enters the first pressing chamber 11 and the second pressing chamber 71, the pressure plate 8 slides below the second pressing chamber 71, sealing the second opening 711. The rotating plate 3 rotates, connecting the feeding channel 21 and the first pressing chamber 11. The shredded material enters the first pressing chamber 11 and the second pressing chamber 71 and remains there. The pressure plate 4 descends to squeeze the shredded material, and simultaneously, the pressure plate 8 cooperates with the pressure plate 4 to squeeze the shredded material, causing it to be pressed into a cake shape in the second pressing chamber 71. After the squeezing is complete, the pressure plate 8 slides, opening the second opening 711, and the cake falls into the transverse channel 51. The pressure plate 8 slides towards the second opening 711, pushing the cake out of the transverse channel 51, thus completing the material discharge.

[0047] The pressure plate 8 works in conjunction with the pressure plate 4 to achieve double-sided extrusion of the shredded material, further improving the compactness and uniformity of the pressed cake. By utilizing the connection between the transverse channel 51 and the second pressing chamber 71, both the extrusion and feeding processes are realized, and the structure of the device is made more compact.

[0048] In some examples, the pressure plate 8 is slidably disposed within the transverse channel 51, and the first telescopic member 9 is disposed on the base 5 and located on one side of the transverse channel 51. The first telescopic member 9 is used to drive the pressure plate 8 to slide, and the pressure plate 8 opens or closes the second opening 711 after sliding.

[0049] For example, such as Figure 1 As shown, during the extrusion process, the first telescopic component 9 moves the pressure plate 8 to a suitable position, closes the second opening 711, and cooperates with the pressure plate 4 to extrude shavings. After extrusion, the first telescopic component 9 retracts first, causing the pressure plate 8 to slide open the second opening 711. After the pressed cake falls into the transverse channel 51, the first telescopic component 9 extends, pushing the pressed cake out of the transverse channel 51.

[0050] The sliding of the pressure plate 8 is controlled by the first telescopic component 9, which opens or closes the second opening 711, facilitating the control of the extrusion and discharge process of the shredded material. The use of the first telescopic component 9 automates the movement of the pressure plate 8, reduces manual operation, and improves work efficiency.

[0051] In some examples, the first semicircular plate 6 and the second semicircular plate 7 are slidably and vertically mounted on the base 5. The transverse channel 51 has a pressing channel 511 and a discharge channel 512 arranged in sequence. The pressing channel 511 is located below the second pressing chamber 71. After the pressure plate 8 slides into the pressing channel 511, it is used to press the shredded material with the pressure plate 4. After the pressure plate 8 slides into the discharge channel 512, it is used to push the pressed shredded material out.

[0052] For example, such as Figure 2As shown, after the shavings enter the second pressing chamber 71, the pressure plate 8 slides down into the extrusion channel 511 driven by the first telescopic member 9, closing the second opening 711. The pressure plate 8 and the pressure plate 4 together extrude the shavings. After extrusion, due to the excessive amount of shavings in the first pressing chamber 11 and the second pressing chamber 71, the height of the pressed cake is greater than the height of the transverse channel 51. In order to achieve the discharge of the pressed cake, the first semi-circular plate 6 and the second semi-circular plate 7 are appropriately raised, lowered, and slid. The pressure plate 8 slides down into the discharge channel 512 driven by the first telescopic member 9, pushing the extruded shavings out.

[0053] The device integrates extrusion and discharge operations, reducing manual intervention and improving production efficiency. The sliding and lifting of the first semi-circular plate 6 and the second semi-circular plate 7, along with the sliding of the pressure plate 8 in different channels, fully utilizes the device's space, resulting in a more compact structure.

[0054] In some examples, the cross-sectional area of ​​the discharge channel 512 is larger than that of the extrusion channel 511, and the first telescopic member 9 is located on the side of the extrusion channel 511 away from the discharge channel 512.

[0055] For example, such as Figure 2 As shown, during the extrusion process, the height of the pressed cake is greater than the height of the extrusion channel 511 of the transverse channel 51, while the discharge channel 512 is designed to be higher than the height of the extrusion channel 511. The pressure plate 8 cooperates with the pressure plate 4 within the extrusion channel 511 to extrude the shavings. After extrusion, the first telescopic member 9 pushes the pressure plate 8 to slide towards the discharge channel 512. Due to the large cross-sectional area and high height of the discharge channel 512, the extruded shavings can be discharged smoothly.

[0056] The cross-sectional area of ​​the discharge channel 512 is larger than that of the extrusion channel 511, providing sufficient space for the extruded shreds and ensuring smooth discharge. The position of the first telescopic component 9 is reasonably set, which facilitates the sliding of the pressure plate 8 between different channels, so as to realize the orderly extrusion and discharge.

[0057] In some examples, the frame 1 has a receiving cavity 12, a guide cavity 13, and a first pressing cavity 11 arranged sequentially from top to bottom. The feeding channel 21 has a feeding port 211, and the feeding port 211 and the rotating plate 3 are located within the receiving cavity 12. The cross-sectional area of ​​the guide cavity 13 decreases sequentially from top to bottom. The base 5 has a mounting groove 52, and the first semi-circular plate 6 and the second semi-circular plate 7 are lifted and slidably disposed within the mounting groove 52.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications or substitutions should be covered within the scope of the claims of this disclosure.
